How do you graph y = -x/5 +4

To factor, we need to find out which 2 numbers add up to -10 and multiples to be 21.

The factors of 21 are 1, 3, 7, 21.

From there, we can conclude that -3 + -7 = -10 and -3 * -7 = 21

Hence when you factor the expression, you get:

(x-3)(x-7)

Work Shown:

[tex]n(A \cup B) = n(A) + n(B) - n(A \cap B)\\\\26 = n(A) + 16 - 5\\\\26 = n(A) + 11\\\\n(A) + 11 = 26\\\\n(A) = 26-11\\\\n(A) = 15\\\\[/tex]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, - 1 ) and (x₂, y₂ ) = (3, - 5 )

m = [tex]\frac{-5-(-1)}{3-5}[/tex] = [tex]\frac{-5+1}{-2}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2

Applying the integral formula, it is found that the expected number of coupons a customer will use is of 1.83.

The probability density function is given by:

[tex]f(x) = \frac{4x + 3}{27}, [0,3][/tex]

The integral formula for the expected value is:

[tex]E(x) = \int_0^3 xf(x) dx[/tex]

Hence, applying the formula for f(x) given in this problem, the expected number of coupons a customer will use is:

[tex]E(x) = \int_0^3 \frac{4x^2}{27} + \frac{x}{9} dx[/tex]

[tex]E(x) = \frac{4x^3}{81} + \frac{x^2}{18}|_{x = 0}^{x = 3}[/tex]

[tex]E(x) = 1.83[/tex]

The expected number of coupons a customer will use is of 1.83.

r = -6

Step-by-step explanation:

The slope of a line is defined as

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

Let [tex]P_1(-4, 2)[/tex] and [tex]P_2(4, r)[/tex]. Since m = -1, we can write

[tex]-1 = \dfrac{r - 2}{4 - (-4)} \Rightarrow -1 = \dfrac{r - 2}{8}[/tex]

or

[tex]r - 2 = -8 \Rightarrow r = -6[/tex]

Answer:

10:5

Step-by-step explanation:

The simplest form of the ratio 10 seconds to 5 min will be;

⇒ 1 : 30

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

The ratio is,

⇒ 10 seconds to 5 minutes.

Now,

Since, The ratio of two numbers has always same units.

So, We change 5 minutes into seconds as;

Since, 1 minutes = 60 seconds

Hence, 5 minutes = 5 x 60 seconds

                            = 300 seconds

Thus, The ratio becomes,

⇒ 10 seconds to 300 seconds

⇒ 10 : 300

⇒ 10 / 300

⇒ 1 / 30

⇒ 1 : 30

Thus, The simplest form of the ratio 10 seconds to 5 min will be;

⇒ 1 : 30

Answer:

  $1 per person

Step-by-step explanation:

The per-person cost (x) can be found from the proportion ...

  x/(0.5 lb) = $8/(4 lb)

Multiplying by 0.5 gives ...

  x = (0.5 lb) × ($8 /(4 lb)) = $1 . . . . . . units of lb cancel

The cost per person will be $1.

Answer:

No

Step-by-step explanation:

Plug the coordinates into the given inequality

2(2) + 3(2) ≤ 10(2) + 4(2) < 10

4 + 6 ≤ 20 + 8 < 10

10 ≤ 28 < 10

(2,2) is not a solution to this system of inequalities since 28 cannot be less than 10.

Answer:

  x = 22.5°

Step-by-step explanation:

The interior angle at E is (180 -4x), the supplement of the exterior angle there, 4x. The sum of angles 2x and (180-4x) will be equal to 6x, because alternate interior angles at transversal BE are congruent:

  2x +(180 -4x) = 6x

  180 = 8x . . . . . . . add 2x and simplify

  22.5 = x . . . . . . . divide by 8

The value of x is 22.5°.

Answer:

The answer to your question is (7.5.4

V=Bh (with B being the area of the base).

h=V/B, or 456/24, or 19.

Answer:

116

Step-by-step explanation:

you can use variables

a+b=110

a+c=112

a+d=113

b+c=118

b+d=121

add up the weights and you get 574 kg (you need to find c+d)

3a+3b+2c+2d=574

a+b+c+d = 230 as given then you multiply by 3 so you can cancel out 3a and 3b and subtract 690-574 because we multiplied by 3

you are left with c+d=116
